I've got a good friend who loves her GSX1100G. She's not an aggressive rider, but loves the ZOOM ZOOM the "Big G" will do. Side by side, her "G" is slightly taller, seems a bit heavier, and a bit more top heavy than my 2 Gen B12S. Unless you are hooked on the tenths of a second in 0-60 jaunts or top speed, the big deal maker/breaker between the two in my mind would be price... For those who prefer a shaft, the "G" is the choice. If all out performance numbers don't impress you as much as price, the "G" is the choice. But, if you want newer, even if it is chain driven, a 2 Gen B12 is a GREAT BUY... power out the wazoo, great stoppers, good ergos, lots of "tinkering toys" to claim your money, great following... If you want to ask my friend direct questions, e-m me ( jrev@cebridge.net ) I'll send you her e-m address.
